DeepMind’s groundbreaking artificial intelligence (A.I.), AlphaGo, defeated Lee Sedol in the final game of the Google DeepMind Challenge Match, winning the five game match with a 4–1 score.

AlphaGo now goes down in history as the 1st computer Go program to defeat a top professional player, and was awarded an honorary professional 9 dan rank by the Korean Baduk Association (note: AG is even ranked nr 2 on http://www.goratings.org/ :-).

Although the match is already won by AlphaGo, the remaining games are played to the full. Lee Sedol won game 4 holding white thanks to a brilliant move in a difficult middle game. This move was even qualified as "god move" by Gu Li, 9p.

This win is quite important from a symbolic point of view. It also exposes some weaknesses of AlphaGo that were invisible so far.

Game 5 will be held on Tuesday 15 March. It has been agreed that Lee Sedol will hold black.

AlphaGo, the go playing software developed by Google Deepmind, has defeated Lee Sedol with three straight wins in their long awaited match!

This amazing achievement comes five months after AlphaGo won 5-0 against Fan Hui. Most of the commentators before the match predicted that AlphaGo had no chance to win against such a strong player as Lee Sedol. However, AlphaGo proved them wrong and edged Lee Sedol in every part of the first three games.

This week end, 16 top European amateurs fought to become the fifth European professional go player.

Ukranian Artem Kachanovskyi beat his countryfellow Andrei Kravets in final and join the four ex-amateurs who already qualified as pros through similar competitions in 2014 (Lisy, Jabarin) and 2015 (Shikshin, Surma).
